Hi,
Recently I am Using Boussinesq coupling with momentum equations in a unsteady heat transfer simulation and I am facing some problems regarding Richardson no.(Ri) as a input parameter for different time step. In my simulation one of the reference temperature(T0) is fixed and another(T1) is changing with time. So temperature difference is changing with time resulting Ri no. changing in each time step. Therefore can I use variable Ri with time in my simulation or am I doing some mistake in my simulation.
If anyone kindly help me in this matter, I shall be highly obliged.
